useful calculator

With the recent passing of Gary Gygax, we were trying to determine what an original Dungeons and Dragons would cost today (10.00 in 1974) and nanoflux and I found this calculator.

This calculator uses all sorts of different methods. We arrive at:

Current data is only available till 2007. In 2007, $10.00 from 1974 is worth:
$42.03 using the Consumer Price Index
$34.47 using the GDP deflator
using value of consumer bundle *
using the unskilled wage *
$65.35 using the nominal GDP per capita
$92.29 using the relative share of GDP

* Data for consumer bundle is only available till 2006.
* Data for unskilled wage is only available till 2006.
